Hi; We've been testing some 1.8.0.1 patchless clients (RHEL5.3, x86_64, RPMs from the Sun download page) with out 1.6.4.2 servers.
The OSS nodes started logging these LustreErrors from the 1.8.0.1 clients: > LustreError: 7302:0:(ost_handler.c:1157:ost_brw_write()) client csum > 8448447f, original server csum 66fb7cff, server csum now 66fb7cff > LustreError: 7302:0:(ost_handler.c:1157:ost_brw_write()) Skipped 1 previous > similar message > LustreError: 7391:0:(ost_handler.c:1095:ost_brw_write()) client csum > 9d8c7d6a, server csum 2cfdcb47 > LustreError: 168-f: ufhpc-OST0004: BAD WRITE CHECKSUM: changed in transit > before arrival at OST from 12345-10.13.28...@tcp inum 38470778/1485322248 > object 67094039/0 extent [0-1023] Is this a known issue with running 1.8.0.1 clients against 1.6.4.2 servers? We aren't seeing these messages in relation to our 1.6 clients. Looking through the Lustre bugzilla, I see bug 18296, which discusses these messages, but it was logged against Lustre version 1.6.6.
